Region : UnitedStates

Model : CPE210

Hardware Version : V2

Firmware Version : V1.1

ISP : Brighthouse Cable


Solved an intermittent WiFi drop out issue on any of (8) CPE210 access points. These AP's connect to the internet via an 8 port gigabit smart switch connected to a 200 MBPS Brighthouse modem/router. All (8) access points were configured using TP-Link's quick setup using progressive independent IP addresses, different channels and different SSID's. All other settings were left at their default settings. The intermittent drop out was caused by the lack of (6) 75 ohm terminators on the open unused ports of the (8) way coax RF splitter that fed the modem/router. A Brighthouse tech had installed an (8) way splitter before the input to the modem/router to lower the DB gain going into the Modem/router. While a DB pad would have been a better choice, the DB gain balancing using the (8) way splitter verses a DB pad accomplished the same results. But leaving the (6) unused open RF ports UN-TERMINATED on the (8) way splitter allowed massive amounts of a DC to daylight RF intrusion into the cable just prior to connection to the modem when any electric motors in the same room were running. After installing (6) 75 ohm terminators to the (6) open unused ports on then (8) way RF coax splitter solved the intermittent drop out of the CPE210's. A spectrum analyzer now shows almost no background RF noise on the coax before input into the modem/router when electrical equipment is in use in the same room as the modem/router. BOTTOM LINE .....check for high RF noise on coax feed from ISP provider before assuming the access points or your network configurations are the problem. Hope this helps some of you out there loosing time and hair on a access point drop out issue similar to my issue.

Thanks for sharing your experience. @Sixhackers

Can you also introduce what does the the (8) way coax RF splitter look like and what is use of it? :confused:

This is a good read, and you will find Why some situations force installers to use coax. http://community.ubnt.com/t5/Getting-Started-Product/Indoor-WiFi-solution-for-a-26-storey-Apartment/td-p/1285073
